does sombody have some data or info abouth corrosion rate of A352LCC with HF and HCl mixture in any ratio! If not this at least in pure Hf and pure Hcl? temperature abouth 40degC.
Thanks

Vol 3 covers HCl and Cl, and Vol 4 covers HF and related.
I believe that you can buy these from NACE for about $300 per volume.
You will find many comments like this:
Neither cast iron nor carbon steel is resistant to hydrochloric acid, even dilute concentrations (<pH 4). Temporary use in emergency situations runs the risk of fire or explosion from hydrogen generated by corrosion.
The tables show corrosion rates for carbon steels at >50mpy at any concentration and any temperature and at zero velocity.
In 36% HCl at 40 C they list 42000 mpy (yes, 42" per year).
In 20% HCl at 25C they list 700mpy
That is another issue, steel will be highly velocity sensitive in this.

Also be aware that contaminated acid can give very different corrosion rates than the pure acid.
